1.创建springboot项目（war）

2.添加tomcat和jstl依赖（pom.xml）

<!-- 1.添加 -->         <dependency>            <groupId>org.apache.tomcat.embed</groupId>            <artifactId>tomcat-embed-jasper</artifactId>            <scope>provided</scope>        </dependency>        <!-- jstl -->        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jstl</artifactId>        </dependency>

3.配置springmvc前缀和后缀（application.properties）

# 前缀spring.mvc.view.prefix=/WEB-INF/jsp/# 后缀spring.mvc.view.suffix=.jsp

4.日志配置（logback.xml）

<?xml version="1.0" encoding="UTF-8"?><configuration>    <!--定义 start  -->    <!-- %m输出的信息,%p日志级别,%t线程名,%d日期,%c类的全名,,,, -->    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">        <encoder>            <pattern>%d %p (%file:%line\)  - %m%n</pattern>            <charset>UTF-8</charset>        </encoder>    </appender>    <appender name="baselog"        class="ch.qos.logback.core.rolling.RollingFileAppender">        <File>log/base.log</File>        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">            <fileNamePattern>log/base.log.%d.%i</fileNamePattern>            <timeBasedFileNamingAndTriggeringPolicy                class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">                <!-- or whenever the file size reaches 64 MB -->                <maxFileSize>64 MB</maxFileSize>            </timeBasedFileNamingAndTriggeringPolicy>        </rollingPolicy>        <encoder>            <pattern>                %d %p (%file:%line\)- %m%n            </pattern>            <charset>UTF-8</charset> <!-- 此处设置字符集 -->        </encoder>    </appender>    <!--定义 end  -->    <!-- 1.默认日志格式并写入文件 -->     <include resource="org/springframework/boot/logging/logback/base.xml"/>    <logger name="cn.wuyang.springboot" level="TRACE" >        <appender-ref ref="baselog" />    </logger></configuration>

5.中文乱码过滤器MyFilter.java

方法一

package cn.wuyang.springboot.filter;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.annotation.WebFilter;/** * 使用注解标注过滤器 * @WebFilter将一个实现了javax.servlet.Filter接口的类定义为过滤器 * 属性filterName声明过滤器的名称,可选 * 属性urlPatterns指定要过滤 的URL模式,也可使用属性value来声明.(指定要过滤的URL模式是必选属性) *  */@WebFilter(filterName="myFilter",urlPatterns="/*")public class MyFilter implements Filter {    @Override    public void destroy() {    }    @Override    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)            throws IOException, ServletException {        request.setCharacterEncoding("UTF-8");        response.setCharacterEncoding("UTF-8");        response.setContentType("text/html;charset=utf-8");        chain.doFilter(request, response);    }    @Override    public void init(FilterConfig arg0) throws ServletException {    }}

方法二

application.properties添加

spring.http.encoding.charset=UTF-8spring.http.encoding.enabled=truespring.http.encoding.force=true

6.配置默认启动页（MyWebAppConfigurer .java）

package cn.wuyang.springboot.config;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;/** * 1.拦截器:继承WebMvcConfigurerAdapter，并重写 addInterceptors 方法。 * 2.自定义资源映射：继承 WebMvcConfigurerAdapter 并重写方法 addResourceHandlers方法  * 3.默认启动方法重写addViewControllers * @author wuyang * */@Configurationpublic class MyWebAppConfigurer extends WebMvcConfigurerAdapter {    @Override    public void addViewControllers(ViewControllerRegistry registry) {        registry.addViewController("/").setViewName("admin/index");        super.addViewControllers(registry);    }}

7.配置热启动pom.xml

首先集成jar包

<!-- 2.热启动 -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-devtools</artifactId>            <optional>true</optional>        </dependency>

其次在

<build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>                <dependencies>                    <!-- 2.热启动   添加-->                     <dependency>                        <groupId>org.springframework</groupId>                        <artifactId>springloaded</artifactId>                        <version>1.2.5.RELEASE</version>                    </dependency>                </dependencies>            </plugin>        </plugins>    </build>

banner生成器
http://www.cnblogs.com/woshimrf/p/banner-ascii-2-txt.html

                                         _______  _        _______              |\     /||\     /||\     /|(  ___  )( (    /|(  ____ \             | )   ( || )   ( |( \   / )| (   ) ||  \  ( || (    \/             | | _ | || |   | | \ (_) / | (___) ||   \ | || |                   | |( )| || |   | |  \   /  |  ___  || (\ \) || | ____              | || || || |   | |   ) (   | (   ) || | \   || | \_  )             | () () || (___) |   | |   | )   ( || )  \  || (___) |             (_______)(_______)   \_/   |/     \||/    )_)(_______)

${AnsiColor.BRIGHT_RED}：设置控制台中输出内容的颜色${application.version}：用来获取MANIFEST.MF文件中的版本号${application.formatted-version}：格式化后的${application.version}版本信息${spring-boot.version}：Spring Boot的版本号${spring-boot.formatted-version}：格式化后的${spring-boot.version}版本信息

9.引入版本号统一

首先在pom.xml 中添加依赖：

<dependency>    <groupId>org.webjars</groupId>    <artifactId>webjars-locator</artifactId></dependency>

然后增加一个WebJarsController：

package cn.wuyang.springboot.controller.base;import javax.servlet.http.HttpServletRequest;import org.springframework.core.io.ClassPathResource;import org.springframework.http.HttpStatus;import org.springframework.http.ResponseEntity;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.HandlerMapping;import org.webjars.WebJarAssetLocator;/** * 处理WebJars，自动读取版本号 * */@Controllerpublic class WebJarsController {     private final WebJarAssetLocator assetLocator = new WebJarAssetLocator();    @ResponseBody    @RequestMapping("/webjarslocator/{webjar}/**")    public ResponseEntity<Object> locateWebjarAsset(@PathVariable String webjar, HttpServletRequest request) {        try {            String mvcPrefix = "/webjarslocator/" + webjar + "/"; // This prefix must match the mapping path!            String mvcPath = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);            String fullPath = assetLocator.getFullPath(webjar, mvcPath.substring(mvcPrefix.length()));            return new ResponseEntity<>(new ClassPathResource(fullPath), HttpStatus.OK);        } catch (Exception e) {            return new ResponseEntity<>(HttpStatus.NOT_FOUND);        }    }}

10.资源名称md5方式

添加 application.properties 配置文件（或.yml）

spring.resources.chain.strategy.content.enabled=truespring.resources.chain.strategy.content.paths=/**

所有 /** 请求的静态资源都会被处理。
创建 ResourceUrlProviderController 文件

package cn.wuyang.springboot.controller.base;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.ControllerAdvice;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.servlet.resource.ResourceUrlProvider;/** * 处理静态资源URL * */@ControllerAdvicepublic class ResourceUrlProviderController {    @Autowired    private ResourceUrlProvider resourceUrlProvider;    @ModelAttribute("urls")    public ResourceUrlProvider urls() {        return this.resourceUrlProvider;    }}

11.集成jquery

我们只需要在pom.xml 文件中添加jquery的webjars 依赖即可，如下

<dependency>    <groupId>org.webjars</groupId>    <artifactId>jquery</artifactId>    <version>3.1.0</version></dependency>

未完待续。。。。。。。。
